An official with the Indian lawn bowls squad has contracted dengue fever – the first person associated with the Commonwealth Games to contract the mosquito-borne disease, which has been a source of concern over athletes' health.

Ruptu Gogoi was staying in the athletes' village, in New Delhi, when he was taken to hospital yesterday.

Dengue fever can be fatal in exceptional cases, but Dr Rajiv Saigol told the Associated Press that Gogoi was in a stable condition at the GB Pant hospital.

"He is eating well. He is sleeping well. He is talking well," Saigol said. "He has some fever, which is quite natural because he has had the problem for four to five days. I am not 100% sure, but maybe he is discharged by tomorrow evening."

It is not clear whether Gogoi contracted the disease at the village or before moving in. Saigol said the lawn bowls squad official would not miss out on the opening ceremony, due to begin at 2.30pm British time.

"We are arranging a television set for him in the hospital because he wants to see Indian athletes marching," he said.

New Delhi has been hit by an outbreak of dengue fever because of the extended monsoon season. The outbreak has been made worse by the ongoing construction work, which has left hundreds of holes filled with rain, creating breeding grounds for mosquitos.

About 3,500 cases of dengue fever have been reported in New Delhi this year, and seven of the afflicted have died, according to the Press Trust of India.

The outbreak is believed to have prompted the withdrawal of scores of top athletes from the games and was one of the factors that led to fears over the past fortnight that the event might have to be cancelled.

Elena Baltacha, Britain's No 1 tennis player, withdrew last week because she has a liver condition linked to her immune system and was concerned about the risks of dengue fever.
